Castillo de Cartaya, also known as the Castillo-fortaleza de los Zúñiga, was constructed between 1417 and 1420 by Don Pedro de Zúñiga with royal license from Juan II of Castilla to defend the passage of the Río Piedras in Huelva, Andalusia. The fortress stands on a rectangular circuit of walls measuring 35 by 27 meters, defended by seven square towers positioned at corners and along front and side stretches. The central tower extends 5 meters in width, while the northwest keep reaches 6 meters, creating an imposing silhouette. Classified as a Bien de Interés Cultural (Cultural Interest Property) since 1985, the castle underwent significant restoration in the 1990s and now hosts cultural events including festivals, choral meetings, music band gatherings, and theatrical performances.
